My present invention relates to an improved nozzle of the type especially adapted for use in fire extinguishers, fire hose, or garden hose, and having a quickly changeable body rotatable about a fixed valve 50 that one of two selected nozzle ports may be used, one port effecting a solid stream, and the other port effecting a fine spray, and the valve having a third position at oil.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised but it will be understood that various changes and alterations may be made in the exemplified structure within the scope of the appended claims.

In the drawings:

Figure 1 is a longitudinal sectional view of the nozzle of my invention.

Figure 2 is an end elevational view thereof.

Figure 3 is a side elevational view of the valve.

Figure 4 is a frontelevational view of the valve.

Figures 5, 6, and 7 are sectional views at line 5 of Figure 1 showing the valve respectively in spray, stream, and off positions.

Figures 8 and 9 are sectional views through the valve and nozzle at lines 88 and 9-9 respectively of Figure 1.

Referring now to the drawings wherein I have illustrated the present preferred embodiment of my invention I employ a nozzle 2 having interior longitudinally extending passages 4 for a solid stream of water and 6 for a spray the orifice of which latter passage has a screen 8.

The other end of the nozzle has a counterbore l0 having a threaded portion I2 to receive the valve body [4 having an annular ring l6 and a port I8 formed with an angular portion 20.

In the periphery of the ring I provide a recess 22 for the ball 24 pressed by spring 26 into one of the recesses 28 in the bore I0.

A securing ring 30 is threaded to engage the portion I2 and is located about the nipple 32 of the valve body which is interiorly threaded to engage the selected hose coupling.

It will be apparent from the above description that the nozzle may quickly and easily be rotated about the valve to either of the three selected positions, to permit the water to flow in a solid' changing from stream to spray or vice versa as the conditions may require.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:

A nozzle comprising a tapered conical shaped body having a counterbore adjacent one end thereof, the outer portion of said bore being provided with screw threads and the portion inwardly of said threads having a smooth surface, a plurality of unobstructed longitudinal passages extending through said body, and said passages communicating with the counterbore, the longitudinal centers of said passages being located at one side of the center of the body and converging toward the outlet ends, a valve body having an annular ring portion adapted to be rotatably received in the portion of the counterbore having a smooth surface, said valve body having a passage one portion of which is in the ring portion and is angularly positioned for selective alignment with the said longitudinal passages and the outer portion of which is engageable with a hose coupling, a threaded securing ring about said last said portion and engaging the threaded portion of said counterbore and in abutment with the ring portion of said valve body to retain said valve body in said bore and means for aligning the passages in selected positions as the first said body is rotated about the valve body. said means comprising a series of recesses in the first said body and spring pressed balls in the valve body located to engage the recesses in the first said body.
